I think these kind of things do help. For people who consume the right kinds of media, there’s lots of coverage of police brutality and I’m sure some of that coverage uses resources like this. If you’re seeing plenty of viral videos then your media consumption is helping you connect with the issue.
Other people rarely or never see coverage though, and aren’t even close to having widespread understanding of the issue of police brutality and it’s relationship with systemic racism, so much more reporting and media production needs to be done.
